2020-3-28 The moisture and, consequently, balling control have a starting point at the comminution process, where several types of equipment is applied in iron ore operations. The comminution process based on HPGR generates a higher fines proportion compared with the ball mill circuit by breaking down the minerals due to the pressure applied over the particles and to a greater extent owing to friction

2021-6-1 2021-6-1 My friend from https://sagmilling/ says most iron ore mines don't use ball mills for a couple of reasons: 1. The grind is coarse enough that you can do it in a single stage (Eg. Labrador Trench) or no grinding is required at all (Pilbara and Brazil direct-shipping iron ores). 2. More cost-effective to use pebble mills instead of ball mills (Eg.

2021-3-15 Progressive depletion of high-grade iron ore reserves resulted in the need to process the lower grade iron ores. Typical lower grade iron ores are represented by itabirites, which are metamorphic banded-iron formations ( Hagemann et al., 2016 ), and consist basically of iron oxide (predominantly hematite), with quartz as the main gangue mineral.
